We divide 5435886 by 840
We want to figure out the number of times 5435886 can be divided by 840.

Step 1:
If we divide 5 by 840, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 840

Moving on to step 2:
54 divided by 840 is 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 840

On to step 3:
840 can be fit into 543 0 times, resulting in a remainder of 543.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 543 after subtracting 0 from 543.
Fetch the next digit (5) from the dividend, attach it to 543 and continue: 5435 / 840

On to step 4:
The number 840 fits into 5435 6 times, leaving a remainder of 395.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 5040 from 5435, we get 395.
Include the next digit (8) from the dividend after 395, then repeat: 3958 / 840

Advancing to step 5:
3958 divided by 840 is 4 with a remainder of 598.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtracting 3360 from 3958 leaves us with 598.
Grab the next digit (8) from the dividend, add it to 598, then carry on: 5988 / 840

Going ahead to step 6:
5988 divided by 840 is 7 with a remainder of 108.
The number 7 becomes the next digit in our result. 
Result so far: 647.0
The remainder is 108 after subtracting 5880 from 5988.
Fetch the next digit (6) from the dividend, attach it to 108 and continue: 1086 / 840

On to step 7:
1086 divided by 840 is 1 with a remainder of 246.
The number 1 becomes the next digit in our result. 
Result so far: 6471.0
If we subtract 840 from 1086, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 8:
2460 divided by 840 is 2 with a remainder of 780.
The next digit of our result is 2. 
Result so far: 6471.2
Subtract 1680 from 2460 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 9:
If we divide 7800 by 840, we get 9 and a remainder of 240.
The next digit of our result is 9. 
Result so far: 6471.29
If we take 7560 away from 7800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 10:
If we divide 2400 by 840, we get 2 and a remainder of 720.
The number 2 becomes the next digit in our result. 
Result so far: 6471.292
Subtract 1680 from 2400 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 11:
The number 840 fits into 7200 8 times, leaving a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 6471.2928
Subtract 6720 from 7200 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 12:
840 can be fit into 4800 5 times, resulting in a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 6471.29285
The remainder is 600 after subtracting 4200 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 13:
6000 divided by 840 is 7 with a remainder of 120.
The number 7 becomes the next digit in our result. 
Result so far: 6471.292857
The remainder is 120 after subtracting 5880 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 14:
1200 divided by 840 is 1 with a remainder of 360.
Record the quotient 1 as the next digit in the result. 
Result so far: 6471.2928571
Subtract 840 from 1200 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
840 goes into 3600 4 times with a remainder of 240.
The next digit of our result is 4. 
Result so far: 6471.29285714
Subtract 3360 from 3600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 6471.29285714, with a leftover of 2.4e-07.
